IMPROVEMENT IN NAIL-MACHINES.

' Specification forming part of Letters Patent No. 58,637, dated October 9, 1866.

To all whom it may concern:

Be it known that I, SIMEON L. GOULD, of Skowhegan, of the county of Somerset and State of Maine, have invented an Improved NailGi1ttirlg Machine; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view, Fig. 2 a side elevation, and Fig. 3 a front elevation, of it. Fig. L is a section taken vertically through one of the vibratory bed-cutters, the nail-plate guidebar, and the feed-rollers. Fig. 5 is a longi tudinal section ot' the nail plate guide-bar. Fig. 6 is a front View of the rotary cutter head or wheel and its cutters.

My invention orimprovement has reference to a machine such as is described in Letters Patent No.27,096, granted February 14, 1860, to Joseph Berry, the object of my principal improvement being to enable two or more nailplates to be cut by the critters oi' the rotary wheel while it may be in revolution. The nailplate vibratory appara-tus of the said machine as made by the said Berry is of such character as to enable but one nail-plate to be vibrated and cut at one time by the cutters of the wheel, the same causing the operations of the machine to be very limited in useful effect in comparison to what can be accomplished by my improvement, by which at least double the number of nails can be cut by the wheel during one revolution to what can be accomplished on the machine of Berry.

While I lay no claim to the application of cutters to the side or open surface of a rotary wheel, I arrange each of such cutters and its socket and clamp-screw so that they may stand at or nearly at rightangles with a radius drawn through the cuttingedge of the cutter. In this way I am enabled to employ two or more sets of cutters in a radial line, and to use very long cutters with a cla1npscrew to each of them. Were two cutter-sockets arranged in a radial line it would be difficult to use more than one clamp-screw. With my arrangement of the cutters and their sockets I can make use of adjusting-screws going through the wheel and against each cutter, whereby it may be adjusted to the proper angle for cutting with the bed-cutter.

In the drawings, A denotes the frame of the l machine, which supports in suitable boxes aa the journals of a horizontal shaft, B, onlwhich is iixed concentrically a circular cuttgr-head, C. This cutter-head carries two or more series of cutters, b b, which are long rectangular plates ot' meta-l placed in rectangular sockets c c, each of which is arranged as shown in the drawingsthat is, at right angles to a radial line passing through oneend ot' it from the axis of the wheel-and each cutter is eonne'd endwise in its socket by means of a clampscrew, d, which screws into the wheel and en ters it from its circumference. There is also to each cutter a wedge-clamp, c, which goes through the wheel transversely and against one edge of the cutter, the same being as shown in Fig. 7, which is a crossvsection ofthe cutter and its wedge-clamp, such clamp being drawn into place by a screw and nut,j".

Fig. 8 is a rear view of the cutter-head, and shows the four adjusting-screws g g g g to each cutter. They screw into the head and against the cutter, and serve to set it at the proper angle to the face of the wheel, so as to enable it to cut a nail of any desirable taper.

The arrangement of the cutters, their clampscrews, and adjusting-screws in the wheel in manner as described and represented not only enables more than one cutter to be used in a radial line, but to apply to each ot' them clamp and adj usting screws, as described.

The shaft B is provided with an eccentric, h, which is spanned by a forked arm, fi, ex tending up from a slide-plate, k, applied to the end ot' the frame. This slide-plate is jointed to two levers or vibratory cutter beds or carriers, l Z, arranged as represented, each serving to support a cut-ter, m. Each of the levers l l is to have a fulcruin, n, extending down through the end baro of the frame. EX- tending over these levers is a guide-bar, p, formed as shown in the drawings, the nail-plates going through the passages b b in such bar. In rear of the said guide-bar are onelong feedroller, q, and two other or shorter feed-rollers, r r, they being arranged as seen in the iigures. The upper feed-rollers are supported in car riers s c, which slide verticallyin a stationary bar, t, and are forced downward by pressuresprings a u. The longer feed-roller is supported in boxes a2 a?, and has" a wormgear, c, iixed on its end. This gear engages with a 2 l 5ans? Worin, w, fixed on a horizontal shaft, x, arranged as represented. A pulley, y, fixed on the shaft m, is to have an endless belt going around it, and another pulley, z, xed on the shaft B, which also has a drivin g-pulley, a', applied to it.

From the above it will he seen that the slideplate k and the eccentric 71, are arranged in front of the Wheel, and that the slide-plate is parallel with the Wheel-face, and when moved moves parallel with such face. By means of such slide-plate and the single long feed-roller and the smaller feed-rollers, arranged as set forth, and by arranging and applying cutters to the Wheel in manner as specied, I am enabled to feedand out two nail-plates at once.

I claim- 1. The arrangement of the slide-plate k and the eccentric It with the vibratory cutter-carrying levers. and the cutter-Wheel and its shaft, or the saine and the feed-rollers and guide-bar, as set forth.

2. The arrangement of the rotary cutters, their sockets, clamping and adjusting screws, and the Wheel or cutter-bed, as specified.

SIMEON L. GOULD.
